trådstjärt Sylviorthorhynchus desmursii

Fairly common but heard much more than seen. This demure little brown bird favors bamboo thickets and other dense tangles at forest edge, roadsides, and along streams. Usually in pairs that move quickly through cover, showing only briefly. Plumage is warm brown overall with paler eyebrow and beady dark eye; might suggest a House Wren but plumage lacks barring, and identified easily if long “wiretail” streamers are seen, such as when flying across a road or trail.
